SUMMARY

The subject disclosure is generally related to side-by-side all terrain vehicles.

Generally, all terrain vehicles (“ATVs”) and utility vehicles (“UVs”) are used to carry one or two passengers and a small amount of cargo over a variety of terrains. Due to increasing recreational interest in side-by-side vehicles, such as those used for trail riding, recreational use, and cargo hauling, such vehicles have entered the market place.

Most side-by-side vehicles include seating for two to three passengers. Side-by-side vehicles, in which the driver and passenger are seated beside each other on laterally spaced apart seats, have become popular because of the ability to allow the passenger to share the driver's viewpoint and riding experience instead of being positioned behind the driver. Two styles of vehicle are known in the marketplace; a first sportive version is known where the driver sits low in the vehicle, as is shown in U.S. Pat. No. 7,819,220 (and corresponding European Patent Publication No. EP 2057060), the subject matter of which is expressly incorporated by reference herein. The second version has the driver seated higher in the vehicle, as is shown in U.S. Patent Application Publication No. 2009/0301830, the subject matter of which is expressly incorporated by reference herein.

In one embodiment described herein, a utility vehicle comprises a plurality of ground engaging members; a frame supported by the plurality of ground engaging members; and an operator area supported by the frame. The operator area includes an operator side and a passenger side.

Rear end 20 is supported by rear wheels 8 and illustratively includes cargo box 22. Additionally, rear end 20 supports a rear suspension 1102, as is detailed herein.

With reference now to FIGS. 43-45, frame 4 will be described in greater detail. As with utility vehicle 2 of FIGS. 1-37, frame 4 of utility vehicle 600 includes front portion 50, mid portion 52, and rear portion 54. As shown in FIG. 43, frame 4 includes channel member 350 centrally positioned on utility vehicle 600. In particular, illustrative channel member 350 generally extends from front portion 50 to rear portion 54. Channel member 350 may be coupled to central frame tubes 60 through conventional means (e.g., welds, bolts, rivets), as best shown in FIG. 44. Channel member 350 generally extends along longitudinal axis L of utility vehicle 600 to provide rigidity and stiffness to frame 4. For example, channel member 350 may increase the bending stiffness of frame 4. Additionally, channel member 350 may cooperate with shear plate 354 (FIG. 3) to increase the torsional stiffness or rigidity of frame 4.

Referring to FIG. 45, illustrative channel member 350 is elevated or raised relative to floor board 300 (FIG. 57) to define an opening or tunnel 604. Tunnel 604 may house a portion of a drive shaft 702 of a powertrain assembly 700. Due to the raised configuration of channel member 350, tunnel 604 may be configured to accommodate drive shafts with larger diameters.

With reference to FIGS. 44 and 45, channel member 350 further includes recessed passageway 353 for receiving other components of utility vehicle 600. In particular, components extending from front end 10 to rear end 20 of utility vehicle 600, such as a wiring harness (lighting, electronic throttle control wiring, etc), cooling tubes, brake lines, and other auxiliary lines or components, etc., may be seated in passageway 353. Illustratively, passageway 353 supports at least one electrical connector or line 601 and/or at least one fluid connector or line 602. For example, lines 601 may be used to provide air flow from front end 10 to rear end 20 of utility vehicle 600 to increase venting and cooling of powertrain assembly 700. Lines 601, 602 may be coupled to channel member 350 with conventional fasteners. It may be appreciated that channel member 350 separates components of utility vehicle 600, for example illustrative channel member 350 separates drive shaft 702 from lines 601, 602.

Additionally, floor board 300 (FIG. 57) may be positioned over channel member 350 and lines 601, 602 in order to cover channel member 350 and lines 601, 602. Alternatively, floor board 300 may include an access panel 606, which may pivot or be removed in order to access channel member 350 and lines 601, 602, as shown in FIG. 57.

Referring to FIGS. 46-48, utility vehicle 600 may include a radiator assembly 610, including a fan 612, a radiator shroud 614, and a coolant supply line 616 coupled to a coolant supply, illustratively a bottle 618. Radiator assembly 610 may be coupled to frame tubes 624 and/or chassis panel 626 at front portion 50 of frame 4 with conventional couplers (not shown).

Radiator shroud 614 extends in forward direction relative to fan 612, as shown in FIGS. 46 and 47. As such, radiator shroud 614 may facilitate air flow in the direction of fan 612, thereby increasing the air flowing into radiator assembly 610. In particular, illustrative radiator shroud 614 is comprised of generally flat portions 620 and corner portions 621. Corner portions 621 may provide a hinging function, for example corner portions 621 may be a living hinge, as best shown in FIG. 48. Corner portions 621 fold, bend, or otherwise move to angle flat portions 620 toward fan 612. As shown in FIG. 48, radiator shroud 614 generally has an illustrative U-shape. Radiator assembly 610 may be coupled with cooling lines 602 (FIG. 47) to cool the components of utility vehicle 600.

With respect to FIGS. 49-51, a winch assembly 630 also may be positioned at front end 10 of utility vehicle 600 and is illustratively positioned generally below radiator assembly 610. Winch assembly 630 may be coupled to chassis panel 626 with conventional fasteners (not shown). Chassis panel 626 may be stamped in order to facilitate coupling between winch assembly 630 and front end 10 of utility vehicle 100. Referring to FIGS. 50 and 51, winch assembly 630 includes a bracket 632, a winch device 634 having a latching member 636, illustratively a hook, a cable 638, and a guide member 640.

Bracket 632 is coupled to chassis panel 626 to support winch device 634. Chassis panel 626 is configured to support bracket 632 without the use of fasteners during installation of winch assembly 630. More particularly, illustrative bracket 632 includes ears 642 that engage with a top surface of chassis plate 626 and bend rearwardly over the top surface of chassis plate 626. In this way, ears 642 support bracket 632 on chassis plate 626 when winch assembly 630 is being coupled to front portion 50 of frame 4 with conventional couplers (not shown), such as bolts or welds. As such, it is not necessary to hold bracket 632 and winch device 634 during installation.

Brush guard 608 also may be mounted to chassis plate 626 at front end 10 of utility vehicle 600. Guide member 640 illustratively is coupled to brush guard 608 with conventional fasteners. As shown in FIG. 51, guide member 640 extends from front end 10 of utility vehicle 600. Referring now to FIGS. 49 and 50, guide member 640 includes an aperture 644 and rollers 646 positioned along each side of aperture 644. Illustratively, aperture 644 is rectangular and rollers 646 are positioned along each of the four sides of aperture 644. In use, latching member 636 and cable 638 may extend through aperture 644 and rollers 646 prevent damage to brush guard 608 and cable 638 when winch assembly 630 is in use.

Referring to FIGS. 52-56, illustrative utility vehicle 600 also includes a powertrain assembly 700 operably coupled to front wheels 6 and/or rear wheels 8. Powertrain assembly 700 includes engine 150 (FIG. 57) and a transmission. As is further detailed herein and best shown in FIG. 52, the transmission may be a continuously variable transmission (“CVT”) 704 positioned rearward of rear roll cage portion 854.

As shown in FIG. 53, illustrative CVT 704 includes a drive side 705 having a drive pulley assembly 706, a driven side 707 having a driven pulley assembly 708, and a belt (not shown) extending therebetween supported in a housing 709. Housing 709 of CVT 704 couples with a cover 710 to house pulley assemblies 706, 708. A clutch air intake system 712 and a clutch exhaust system 714 are included on CVT 704. Clutch air intake system 712 provides air to both drive pulley assembly 706 and driven pulley assembly 708, and the air exits CVT 704 through clutch exhaust system 714.

Clutch air intake system 712 is illustratively positioned rearward of passenger seat 36 and upright portion 870 of rear roll cage portion 854 (FIG. 52). Referring to FIGS. 53-56, clutch air intake system 712 includes an air intake tube 713 removably coupled to an inlet port 716 with fasteners 720. Inlet port 716 may be divided into various channels, for example inlet channels 746 and 750, as is further detailed herein. Illustratively, inlet channels 746, 750 are angled away from each other and form a “Y” or “V” shape. Air intake tube 712 also is coupled to a first intake member 722, which may be supported on rear roll cage portion 854 (FIG. 52) with conventional fasteners (not shown). First intake member 722 may be comprised of a generally rigid material (e.g., high density polyethylene) and coupled to a second intake member 724 with a fastener 726. Additionally, second intake member 724 is illustratively coupled to a filter support member 728 and a filter cover 730. Illustrative air intake tube 713 and second intake member 722 are comprised of a flexible material.

As shown in FIG. 52, filter support member 728 (FIG. 53) may be coupled to a side panel 842 of cab 840 and is positioned rearward of rear roll cage portion 854. Filter cover 730 includes a frame portion 732 and filter portions 734. Filter portions 734 may be comprised of a mesh or other finely-woven material to provide a pre-filtering function for CVT 704. Frame portion 732 generally extends around each filter portion 734. Illustratively, filter cover 730 includes at least three filter portions 734.

Referring to FIGS. 54 and 55, clutch exhaust system 714 is positioned rearward of operator area 30 and includes a flexible exhaust tube 715 coupled to an exhaust port 718. Exhaust tube 715 includes a tab or support 736 that secures a catch filter 738 to exhaust tube 715. In particular, a top portion of catch filter 738 includes at least one opening 740 to receive tab 736. Catch filter 738 prevents debris from entering clutch exhaust system 714. Illustrative exhaust tube 715 further includes supports 742, which may stabilize wires or other lines at rear end 20 of vehicle 700.

Clutch air intake system 712 and clutch exhaust system 714 are modular systems comprised of multiple components removably coupled to each other. More particularly, air intake tube 713 is removably coupled to inlet port 716 and first intake member 722. Similarly, second intake member 724 is removably coupled to first intake member 722 and filter support member 728. Likewise, exhaust tube 715 is removably coupled to exhaust port 718 and catch filter 738. In this way, clutch air intake system 712 and clutch exhaust system 714 of CVT 704 may be easily assembled without needing to re-tool other attachments. Additionally, the modular arrangement of clutch air intake system 712 and clutch exhaust system 714 allows the various components to be easily replaced and/or interchanged.

Housing 709 of CVT 704 is shown in FIG. 56 with cover 710 removed. Housing 709 includes a wall 744 extending around drive side 705 and driven side 707 of CVT 704. Drive side 705 includes inlet channel 746 of inlet port 716 and a duct or passageway 748 generally extends from inlet channel 746. Similarly, air is directed to drive side 707 through inlet channel 750 of inlet port 716 and a duct or passageway 752 generally extends from inlet channel 750. Passageways 748, 752 may be molded into housing 709 through conventional forming techniques.

As detailed above, inlet channels 746, 750 are angled away from each other such that clutch air intake system 712 provides at least two different, but simultaneous, flows of air through CVT 704. Air from drive side 705 and air from driven side 707 may combine near the bottom of wall 744 and flow together toward exhaust port 724 (FIG. 55). In this way, clutch air intake system 712 may split or divide incoming air between drive side 705 and drive side 707 of CVT 704. However, all air in CVT 704 exits through a common outlet, in particular, exhaust port 718 of clutch exhaust system 714. In one embodiment, the tangential area of clutch exhaust system 714 is increased to facilitate air flow through exhaust tube 715.

CVT 704 is operably coupled to engine 150. During operation, engine 150 may be lubricated with a fluid, for example oil. As shown in FIG. 57, an oil cap 760 may be coupled to the top surface of engine 150. Oil cap 760 allows excessive pressure in the crankcase system of engine 150 to be vented while continuing to maintain the pressure in the crankcase system at, or below, a predetermined level. Referring to FIG. 58, oil cap 760 includes a cap portion 762 and a body portion 764, illustratively a pressure-relief valve. Body portion 764 may be positioned within engine 150, however cap 762 couples with the top surface of engine 150. The illustrative embodiment of oil cap 760 is comprised of a nylon material, however, other suitable materials may be used. An o-ring or other sealing member 766 may be received within a groove 768 and extends between body portion 764 and the top surface of engine 150 to seal oil within engine 150.

Illustratively, as best shown in FIG. 58, body portion 764 includes upper end 764 a, a lower end 764 b, and a plurality of internal channels 770 extending therebetween. Channels 770 intersect with an upper seal 772, illustratively a lip seal, which may be press fit or otherwise coupled to body portion 764. Upper seal 772 has a circular shape and extends around an inner surface 774 of body portion 764. Upper seal 772 includes a circular lip 776 that engages inner surface 774 to close internal channels 770. Lip 776 is comprised of a flexible polymeric material and may move away from inner surface 774 when pressure is applied to lip 776. Additionally, upper end 764 a of body portion 764 includes a plurality of openings 778 above channels 770.

The illustrative embodiment of oil cap 760 is configured to vent pressure from engine 150, and more particularly, from a closed crankcase system of engine 150. For example, if vehicle 600 is used at low ambient temperature, the breather or exhaust means of engine 150 may freeze or otherwise be compromised. However, oil cap 760 is configured to release pressure from engine 150. In particular, pressure from engine 150 may act on internal channels 770 and, therefore, on upper seal 772. Lip 776 may be pushed away from inner surface 774 by the pressure in channels 770 to provide a passageway from internal channels 770 to openings 778. When lip 776 is pushed away from inner surface 774, pressure is able to vent from engine 150, through internal channels 770, past upper seal 772, and exit through openings 778. It may be appreciated that cap portion 762 directs the venting pressure downwardly toward the top surface of engine 150. In this way, external fluids are prevented from entering openings 778 and engine 150.

Referring to FIGS. 59-61, an air box assembly 780 is operably coupled to engine 150. In particular, air box assembly 780 draws air into engine 150 to facilitate combustion. As shown in FIG. 59, air box assembly 780 includes a lid 782, a base 784, a plurality of hoses 786 to transport air, a hinge assembly 788 for coupling lid 782 to base 784, and a filter 796 (FIG. 60). Referring now to FIG. 60, filter 796 contains debris or other matter to prevent such matter from entering engine 150. Additionally, if filter 796 is dirty (i.e., contains debris), the debris on filter 796 from entering engine 150.

Hoses 786 are coupled to base 784 and lid 782 and, more particularly, hose 786 b is coupled to base 784 and hose 786 c is coupled to lid 782. Hose 786 b is further coupled to hose 786 a with a fastener 792. Hose 786 a also is coupled to an intake port 794, which is coupled to a side panel 844 of cab 840 and is positioned rearward of rear roll cage portion 854 and driver's seat 34. Hoses 786 b, 786 c may be comprised of a flexible, polymeric material, however, hose 786 a may be comprised of a rigid material.

Referring to FIG. 61, filter 796 is positioned intermediate lid 782 and base 784. Lid 782 may pivot relative to base 784 about hinge assembly 788. In particular, lid 782 and base 784 form a “clamshell” arrangement. Hinge assembly 788 includes posts 798 coupled to base 784 and cover members 799 coupled to lid 782. Posts 798 are received within cover members 799. Cover members 799 retain posts 798 therein such that lid 782 may be pivoted or rotated about posts 798 and remain coupled to base 784. In this way, hinge assembly 788 prevents lid 782 from separating from base 784, however, hinge assembly 788 allows lid 782 to rotate relative to base 784. Hinge assembly 788 further provides an orienting function for lid 782 and base 784. More particularly, hinge assembly 788 properly aligns and orients lid 782 with base 784. In addition to hinge assembly 788, air box assembly 780 may include closing members 790 to further secure lid 782 to base 784.

As shown in FIGS. 62 and 63, fuel tank 260 supplies fuel to engine 150 for operation thereof and may be positioned in a generally inboard location under driver's seat 34. Illustrative fuel tank 260 includes at least a fuel filter 800, for example a roll-over valve, coupled to a top surface of fuel tank 260 and a fuel fill cup 1050 extending from a side portion of fuel tank 260. Referring to FIG. 66, if pressure in fuel tank 260 increases, the pressure may be relieved through fuel filter 800 and hose 828. Additionally, the arrangement of fuel filter 800 may prevent external fluids from entering fuel filter 800 and, therefore, fuel tank 260.

Referring to FIGS. 64 and 65, the arrangement of fill cup 1050 allows fuel tank 260, which is located at an inboard, or generally central, location of vehicle 600, to be filled at an outboard side of vehicle 600, for example at side panel 844 (FIG. 40). Illustrative fill cup 1050 includes a fill tube 1052 and a chamber 1054 generally surrounding fill tube 1052.

Chamber 1054 includes a proximate end 1068, a distal end 1070, and a side wall 1072 extending therebetween. Proximate end 1068 may be substantially flat and perpendicular to fill tube 1052. Distal end 1070 may have a curved or rounded shape that extends into a neck 1074. Neck 1074 couples with a hose 1076 to direct fuel into fuel tank 260. Conventional fasteners (e.g., clamps) may be used to secure hose 1076 to neck 1074 and to fuel tank 260. Illustratively, neck 1074 has a smaller diameter than chamber 1054 and hose 1076.

Chamber 1054 has a generally cylindrical shape and may have a diameter of approximately three inches. Additionally, the length of illustrative side wall 1072 may be approximately 2.5 inches. However, the size of chamber 1054 may vary, depending on the vehicle and other parameters. Furthermore, the length of side wall 1072 may be established by determining the length required to properly align a fuel nozzle and the volume required to contain fuel in chamber 1054. As such, these two requirements are considered and balanced in order to determine the dimensions of side wall 1072.

The illustrative embodiment of fill tube 1052 is defined by a diameter of approximately two inches. Fill tube 1052 includes an exterior portion 1062 and an interior portion 1060. Illustratively, proximate end 1068 is intermediate interior portion 1060 and exterior portion 1062. Exterior portion 1062 extends outwardly from fill cup 1050 to define an aperture 1058 to receive a fuel nozzle. Exterior portion 1062 also may be threaded to receive a fuel cap 1064 thereon. Additionally, interior portion 1060 extends into chamber 1054 to define a channel 1056 to receive and guide the fuel nozzle toward neck 1074. More particularly, interior portion 1060 directs the fuel nozzle toward a center portion of chamber 1054 and neck 1074, thereby preventing the fuel nozzle from directly contacting neck 1074 when fuel is being supplied to fuel tank 260. An inner surface 1064 of interior portion 1060 is substantially smooth and properly aligns the fuel nozzle toward hose 1076. An outer surface 1066 of interior portion 1060 has a tapered shape to allow more fuel to accumulate in chamber 1054 and, therefore, prevents spilling when fuel tank 260 is full.

In operation, illustrative fuel cup 1050 has a fill rate of approximately 10 gallons/minute. Additionally fuel cup 1050 allows fuel tank 260 to be filled with a five-gallon gas can and maintains sufficient fuel fill quality while also allowing vapors to vent from fuel tank 260. While fuel is entering fuel tank 260 through fill tube 1052, vapors may simultaneously exit fuel tank 260 through fill tube 1052. In particular, the diameter of fill tube 1052 accommodates a fuel nozzle and also provides sufficient clearance for vapors to exit.

As the fuel nozzle shuts off when fuel tank is full, any excess fuel flowing from fuel tank 260 may be contained within chamber 1054. By containing excess fuel in chamber 1054, the fuel is prevented from overflowing and spilling from fill tube 1052. The arrangement of fill cup 1050 has the effect of slowing down the rate of fuel flowing toward fill tube 1052. Furthermore, the arrangement of fill tube 1052 and chamber 1054 separates the vapors that exit through fill tube 1052 from the liquid fuel that is contained within chamber 1054.

Referring to FIGS. 94-98, rear end 20 of vehicle 600 is supported by rear wheels 8 and rear suspension assembly 1102. Rear suspension assembly 1102 may include components similar to those of the suspension assembly of FIGS. 12 and 13 and, illustratively, includes an upper alignment arm 1104 and a lower alignment arm 1106. As shown, both upper and lower alignment arms 1104, 1106 have a rounded outer end that connects to a hub 1108. More particularly, hub 1108 coupled with upper and lower alignment arms 1104, 1106 at a center portion of the rounded end of arms 1104, 1106. Illustratively, hub 1108 may be coupled to upper and lower alignment arms 1104, 1106 generally forward of the center portion of the rounded ends. Each of hubs 1108 includes a spindle 1110, which rotates along an axis generally transverse to the longitudinal axis L (FIG. 41). Lower alignment arms 1106 further comprise a lower plate portion 1112 which supports a bracket 1114 for a mounting arm 1118 of a torsion or sway bar 1120. A shock absorber 1116 also may be supported on lower plate portion 1112 and spaced apart from bracket 1114 and mounting arm 1118.

Additionally, FIGS. 94 and 95 disclose two stub shafts or half shafts 1122 spaced apart from each other. Each half shaft 1122 is operably coupled to one of the hubs 1108. In particular, each half shaft 1122 extends between shock absorber 1116 and mounting arm 1118. Illustratively, rear portion 20 of vehicle 600 is elongated. More particularly, the length of rear portion 20 of vehicle 600 may be increased by at least two inches relative to that of vehicle 2. As such, half shafts 1122 may extend in a generally horizontal direction such that each half shaft 1122 is substantially perpendicular to longitudinal axis L of vehicle 600. Alternatively, half shafts 1122 may sweep forward toward front end 10 of vehicle 600, depending on the length of rear end 20.

As shown in FIGS. 97 and 98, rear suspension 1102 is coupled to frame 4. Vertically extending channels 1124 of frame 4 extend at each side of rear end 20 and define locations for mounting upper and lower alignment arms 1104, 1106. Conventional fasteners, such as bolts, adhesive, and rivets, may be used to couple upper and lower alignment arms 1104, 1106 with channels 1124. More particularly, the ends of illustrative upper and lower alignment arms 1104, 1106 include generally cylindrical coupling portions 1126, 1128, respectively. Coupling portions 1126, 1128 may be generally hollow and are configured to receive a bushing or other similar component therein. Fasteners 1130 are used to secure coupling portions 1126, 1128 of upper and lower alignment arms 1104, 1106, respectively, to frame 4.

An upper end 1132 of shock absorber 1116 also may be coupled to frame 4 with conventional fasteners (not shown). With respect to FIG. 97, upper end 1132 is received within a bracket 1134 of a frame arm 1136 in order to support shock absorber 1116 on frame 4.

Referring now to FIGS. 67-71, vehicle 600 further comprises roll cage 850, which generally surrounds operator area 30 and defines cab 840. As shown in FIG. 70, roll cage 850 includes a front roll cage portion 852 and rear roll cage portion 854. Front roll cage portion 852 includes upright portions 856, an overhead beam 858 (FIG. 69) defining a surface 860, and a lower beam 862 defining a surface 864. Surface 860 illustratively includes a plurality of apertures 861.

As shown in FIG. 99, front roll cage portion 852 is coupled to frame 4 with brackets 857 and is coupled to rear roll cage portion 854 with crossbeams 866 and rear connectors 868. In particular, brackets 857 may be coupled to upright portions 856 with conventional fasteners or, alternatively, may be integral therewith. Illustrative brackets 857 are L-shaped and include a generally right-angle bend. More particularly, brackets 857 fold over frame member 1140 to couple roll cage 850 to frame 4. Fasteners 1142 extend through brackets 857 in order to couple upright portions 856 to frame member 1140.

Rear roll cage portion 854 includes upright portions 870, cross members 872, 874, 876, and diagonal braces 878. Cross member 872 illustratively includes a plurality of apertures 873 (FIG. 71). Additionally, side supports 880 extend forwardly from upright portions 870. Front roll cage portion 852 may be removably coupled to rear roll cage portion 854 with conventional fasteners 846. In this way, upright portions 856, overhead beam 858, lower beam 862, crossbeams 866, and rear connectors 868 may be removed from rear roll cage portion 854.

Rear roll cage portion 854 is coupled to frame 4 with conventional fasteners. In particular, upright portions 870 may be coupled to brackets 1152 at each side of vehicle 600. As shown in FIGS. 68-71, upright portions 870 are received within a top portion 1154 of brackets 1152 and may be retained therein with conventional fasteners. Illustratively, top portion 1154 is larger than upright portions 870 such that upright portions 870 are received within approximately half of top portion 1154. Top portion 1154 is coupled to frame 4, for example a frame member 1150, and a lower portion 1156 that is angled inwardly and coupled to other members (not shown) of frame 4. Brackets 1152 may also support a portion of doors 886, as is further detailed herein.

As shown in FIGS. 72 and 73, upright portions 856 of front roll cage portion 852, crossbeams 866, rear connectors 868, and upright portions 870 of rear roll cage portion 854 may each include a profiled cross-section. For example, upright portions 856, 870, crossbeams 866, and rear connectors 868 may form a generally figure-eight or hourglass shape in cross-section (see FIG. 73). As such, upright portions 856, 870, crossbeams 866, and rear connectors 868 include contoured portions defining an inner recessed surface 891 a and an outer recessed surface 891 b. Illustratively, when upright portions 856 and 870 are coupled together via crossbeams 866 and rear connectors 868, outer recessed surface 891 b defines a substantially continuous lip 882 formed at the perimeter of roll cage 850. Lip 882 allows accessories, such as doors 886, to be flush with roll cage 850 when coupled thereto, as is further detailed herein.

Cab 840 further includes roof 884, doors 886, front windshield 888, and rear windshield 890. In this way, cab 840 may be enclosed or isolated from other portions of vehicle 600. Roof 884 is coupled to overhead beam 858 and surface 860 of front roll cage portion 852, and also is coupled to cross member 872 of rear roll cage portion 854. Illustratively, roof 884 rests on top of crossbeams 866 but alternative embodiments of vehicle 600 may include couplers for further securing roof 884 to crossbeams 866. More particularly, surface 860 and crossbeams 866 each include inner recessed surfaces 891 a, which may engage a sealing member 893 to form a seal between roof 884 to roll cage 850, thereby further contributing to the isolation of cab 840.

Roof 884 includes an outer panel 892 coupled to an inner panel 894. Referring to FIG. 74, outer panel 892 includes stiffening ribs 896 to support outer panel 892 and locating members 898 to secure outer panel 892 to roll cage 850. Locating members 898 may be integrally formed with outer panel 892 and project therefrom. Additionally, outer panel 892 may be configured to support a plurality of accessories. For example, outer panel 892 may include a dome light portion 900, channels 902 for securing wiring therein, and/or a rear light portion 904.

Inner panel 894 may be coupled to roll cage 850 and outer panel 892 with fasteners 851. To couple with roll cage 850, inner panel 894 includes tabs 895 which extend outwardly. As shown in FIG. 73, tabs 895 rest atop inner recessed surfaces 891 a and are secured between crossbeams 866 and sealing member 893. As such, when outer panel 892 is coupled to roll cage 850, pressure is applied to tabs 895 to secure inner panel 894 to roll cage 850. Inner panel 894 also may support various accessories, such as a dome light (not shown) and speakers (not shown). In particular, inner panel 894 may include a dome light portion 906, as well as speaker portions 908.

As shown in FIGS. 74-77, roof 884 is illustratively coupled to roll cage 850 without fasteners. Locating members 898 couple roof 884 to roll cage 850 and, more particularly, locating members 898 are received within apertures 861 of surface 860 at front roll cage portion 852. Additionally, locating members 898 are received within apertures 873 of cross member 872 of rear roll cage portion 854. In this way, outer panel 892 is snapped or latched on to roll cage 850. Therefore, it is not necessary to use fasteners for coupling roof 884 to roll cage 850 and, as such, roof 884 may be easily installed and removed from vehicle 600.

With reference to FIGS. 67-69, cab 840 may include front windshield 888. In particular, front windshield 888 extends horizontally between upright portions 856 and extends vertically between overhead beam 858 and lower beam 862. Front windshield 888 may be stamped to facilitate installation thereof. Stamping also allows front windshield 888 to form a solid surface. Along with roof 884, front windshield 888 further encloses and isolates cab 840. However, a duct at the top of front windshield 888 may be included in order to provide air flow into cab 840. Alternatively, roof 884 may include a duct that supplies air to cab 840.

Referring to FIG. 69, the illustrative embodiment of front windshield 888 is generally frameless and does not include supports. Front windshield 888 is comprised of a generally transparent material, for example laminated safety glass or tempered glass. Front windshield 888 may be coupled to roll cage 850 with retention clips 910 coupled to surface 860 and surface 864. As shown in FIG. 70, at least two retention clips 910 may be included on surface 860, and at least two retention clips 910 may be included on surface 864 to secure the top and bottom of front windshield 888 to roll cage 850, respectively. Front windshield 888 may be retained within retention clips 910, rather than with conventional fasteners, such as bolts or screws (FIG. 78). Alternatively, retention clips 910 may be coupled to front windshield 888, such that a portion of surfaces 860, 864 are retrained by retention clips 910.

Retention clips 910 may be configured to rotate between an open position and a closed position in order to install front windshield 888 on roll cage 850 or remove front windshield from roll cage 850. More particularly, the open position rotates retention clips 910 to a generally vertical orientation and the closed position rotates retention clips to a generally horizontal orientation.

Alternatively, clamping devices (not shown), such as Lock & Rides clamps, may be coupled to front windshield 888 and upright portions 856 of front roll cage portion 852. As such, the clamping devices may closed or locked in order to secure front windshield 888 to roll cage 850, or opened or released to remove front windshield 888 from roll cage 850.

Other alternative embodiments of front windshield 888 may be configured to pivot or rotate relative to roll cage 850. The illustrative front windshield 888 of FIG. 80 may include a frame 1208 that generally borders front windshield 888. As shown in FIGS. 79-84, a hinge assembly 916 may be coupled to an upper portion of front windshield 888 and to surface 860 of roll cage 850. Hinge assembly 916 includes a top hinge 918 coupled to a bottom hinge 920 with a pin 922. Top hinge 918 may be coupled to surface 860 with conventional fasteners 924, for example bolts, screws, rivets, or welds. Similarly, bottom hinge 920 may be coupled to front windshield 888 with conventional fasteners (not shown). Bottom hinge 920 is configured to pivot relative to top hinge 918 and about pin 922 in order to rotate front windshield 888 between an open position and a closed position, as further detailed herein.

A lower portion of front windshield 888 may be coupled to surface 864 with a latch assembly 926. Referring to FIGS. 80-83, latch assembly 926 is coupled to the center of the lower portion of front windshield 888 and is further coupled to surface 864. Latch assembly 926 includes a handle 928; a body portion 929 having a first aperture 930 and a second aperture 932; a pin 934; and a support member 936. Latch assembly 926 is positioned rearwardly of front windshield 888 and, as such, is accessible from operator area 30.

Latch assembly 926 cooperates with hinge assembly 916 to pivot front windshield 888 between first and second open positions (FIGS. 83 and 84) and a closed position (FIG. 81). Additionally, front windshield 888 includes at least one shock or spring 940 to secure front windshield 888 in the second open position, as further detailed herein.

In particular, when front windshield 888 is in the closed position, handle 928 is in a downward position and pin 934 is received through first aperture 930, as best shown in FIG. 81. When it is desirable to open front windshield 888, handle 928 may be pulled or rotated upwardly against a cam surface of body portion 929 to disengage pin 934 from first aperture 930, as best shown in FIG. 82. Front windshield 888 may then be pushed outwardly in order to open to the first open position (FIG. 83). In the first open position shown in FIG. 83, the lower portion of front windshield 888 is spaced apart from surface 864 and second aperture 932 of handle 928 receives pin 934. In this way, front windshield 888 remains approximately parallel to surface 864 and upright portions 856, but provides additional ventilation to operator area 30.

Alternatively, it may be desirable to rotate front windshield 888 to the second open position, wherein front windshield 888 may be approximately parallel to the ground. As shown in FIG. 84, front windshield 888 may be released from the closed position by rotating handle 928 upwardly and disengaging pin 934 from first aperture 930. Front windshield 888 may then be pivoted forward from roll cage 850 when handle 928 is released from pin 934. As such, front windshield 888 and handle 928, may be pivoted forward to extend above surface 864. Locking devices, for example rods, springs, or other supports, and illustratively shocks 940, may be coupled to the outer sides of front windshield 888 and to upright portions 856 of front roll cage portion 852. Shocks 940 extend linearly when front windshield is rotated to the second open position. Shocks 940 support front windshield 888 in the second open position.

To close front windshield 888, latch assembly 926 may be used to pull windshield 888 rearwardly to the closed position. Pin 934 may be received through first aperture 930. Handle 928 may rotate downwardly along the cam surface of body portion 929 when front windshield 888 engaged surface 864 in the closed position.

Front windshield 888 may further include a windshield wiper having an arm 912. A support plate 913 (FIG. 105) may be comprised of a rigid material (e.g., steel, aluminum) and coupled to front windshield 888 to support windshield wiper arm 912. Support plate 913 may be supported on an encapsulation or overmold portion 1250 (FIG. 100), as is further detailed herein. Front windshield 888 includes a motor assembly 1200 operably coupled to wiper arm 912 and also supported by support plate 913 and overmold 1250 (FIG. 80). Motor assembly 1200 includes a motor 1202, an electrical line 1204, and a connector 1206 for electrically coupling to the electrical system of vehicle 600. For example, illustrative connector 1206 may be a plug that couples with an electrical line (not shown) supported by roof 884. In operation, motor assembly 1200 permits wiper arm 912 (FIG. 87) to move along front windshield 888. Motor 1202 may include various settings or modes, such as slow, fast, and intermittent, to control the speed of wiper arm 912.

Windshield wiper arm 912 may be operably coupled to a container body 914 having washer fluid for cleaning front windshield 888 (FIG. 85). Container body 914 may be positioned rearward of cab 840 and adjacent CVT 704 and engine 150. In this way, the heat from engine 150 and CVT 704 may prevent the washer fluid within container body 914 from freezing when vehicle 600 is used at low temperatures.

Referring to FIGS. 100-106, front windshield 888 is comprised of a laminate safety glass or other transparent material. Front windshield 888 may include overmold 1250, which is comprised of a polymeric material, for example urethane. Overmold 1250 is bonded to an upper portion of front windshield 888. Additionally, overmold 1250 may be bonded to support plate 913, hinge assembly 916, in particular bottom hinge 920, and/or frame 1208. In particular, overmold 1250 surrounds support plate 913 such that support plate 913 is encapsulated within overmold 1250. Overmold 1250 also partially encapsulates a lower portion of bottom hinge 920. As such, overmold 1250 bonds together front windshield 888, support plate 913, and bottom hinges 920. An upper portion of frame 1208 also may be bonded to overmold 1250. In this way, during assembly, front windshield 888, support plate 913, wiper arm 912, motor assembly 1200, frame 1208, and overmold 1250 may be assembled to front roll cage portion 852 as a single unit.

With reference to FIGS. 100-104, overmold 1250 includes a linear portion 1258, a central portion 1256, and hinge portions 1254. Hinge portions 1254 encapsulate or generally surround the lower portion of bottom hinges 920 and bonds bottom hinges 920 to front windshield 888. Similarly, central portion 1256 encapsulates support plate 913 to bond support plate 913 to front windshield 888. Also, central portion cooperates with support plate 913 to support motor assembly 1200 and wiper arm 912 on front windshield 888. Linear portion 1258 is bonded directly to a top portion of front windshield 888. As shown in FIG. 104, a top portion, specifically a top corner, of front windshield 888 includes an angled surface 1262. Linear portion 1258 of overmold 1250 includes a complementary angled surface 1264 that corresponds to, and bonds with, angled surface 1262.

A sealing member 1260 may be coupled to front windshield 888 and overmold 1250. As shown in FIGS. 100 and 103, sealing member 1260 generally follows the shape of front windshield 888 and overmold 1250. In particular, sealing member 1260 includes an opening 1270 that receives at least a portion of linear portion 1258 of overmold 1250. The thickness of opening 1270 is generally equal to the thickness of linear portion 1258, such that linear portion 1258 is frictionally coupled to sealing member 1260.

As shown best in FIG. 101, the thickness of front windshield 888 is substantially equal to the thickness of linear portion 1258, such that linear portion 1258 of overmold 1250 is flush with front windshield 888. As such, the thickness of front windshield 888 also is generally the same as the thickness of opening 1270 of sealing member 1260. As shown in FIGS. 101 and 106, front windshield 888 may be curved to increase visibility and better couple front windshield 888 with front roll cage portion 852. Because linear portion 1258 is flush with front windshield 888, overmold 1250 also includes the same radius of curvature as front windshield 888. Additionally, because sealing member 1260 follows the general shape and contour of front windshield 888, sealing member 1260 also generally includes the same radius of curvature of front windshield 888.

During assembly, support plate 913 and bottom hinges 920 are bonded to front windshield 888 with overmold 1250. In particular, support plate 913, bottom hinges 920, and front windshield 888 are positioned within an enclosed mold or die. A polymeric material (e.g., urethane) is injected into the mold and flows to surround the lower portion of bottom hinges 920, support plate 913, and the top portion of front windshield 888, thereby defining overmold 1250. When cooled, front windshield 888, bottom hinges 920, and support plate 913 are bonded together with overmold 1250. Alternative embodiments may couple the top portion of frame 1208 with overmold 1250 in the same manner.

Generally opposite from front windshield 888 is rear windshield 890. As shown in FIG. 68, rear windshield 890 may be coupled to cross members 872, 874. As with front windshield 888, retention clips 944 may be used to retain rear windshield 890 on rear roll cage portion 854 (FIG. 86). For example, two retention clips 944 may be coupled to cross member 872 to secure the top portion of rear windshield 890, and two retention clips 944 may be coupled to cross member 874 to secure the bottom portion of rear windshield 890. As shown in FIG. 68, retention clips 944 are positioned outward, or rearward, of rear windshield 890

Alternatively, rear windshield 890 may be coupled to rear roll cage portion 854 with upper clamps 946 and lower clamps 948. Referring to FIGS. 87 and 88, clamps 946 and/or 948 may be lock-and-ride clamps. For example, the top portion of rear windshield 890 may include at least two upper clamps 946, which are configured to rotate between an open or generally horizontal position and a closed or generally vertical position. As shown in FIG. 88, upper clamps 946 may be pivoted to the open position when installing rear windshield 890 on rear roll cage portion 854. In this way, upper clamps 946 do not interfere with cross member 872. However, when the top portion of rear windshield 890 is engaged with rear roll cage portion 854, upper clamps 946 may be pivoted to the closed position to retain rear windshield 890 on rear roll cage portion 854. Additionally, the bottom portion of rear windshield 890 may include lower clamps 948, which extend around, and clamp to, a coupling surface 950 on cross member 874. In this way, both the top portion and the bottom portion of rear windshield 890 are secured to rear roll cage portion 854. Upper clamps 946 and lower clamps 948 may be coupled to an inner surface of rear windshield 890 such that upper and lower clamps 946, 948 are accessible from operator area 30. It is to be understood that front windshield 888 may include clamps, such as clamps 946, 948 to secure front windshield 888 to front roll cage portion 852 in a similar manner.

Referring to FIGS. 89-91, doors 886 may be coupled to front and rear roll cage portions 852, 854 to further enclose cab 840 and operator area 30. Additionally, doors 886, along with roof 884, add to the weight of vehicle 600 and may shift the center of gravity of vehicle 600.

Doors 886 are illustratively full doors that enclose roll cage 850. Alternatively, doors 886 may be half doors that do not extend above front and rear windshields 888, 890. Doors 886 are removably hinged at rear roll cage portion 854 such that doors 886 open at front roll cage portion 852 and swing rearwardly toward rear roll cage portion 854. However, doors 886 may be coupled to roll cage 850 such that doors 886 open at rear roll cage portion 854 and swing forwardly toward front roll cage portion 852. Doors 886 may be flush with roll cage 850 because doors 886 may engage lip 882 (see FIG. 73). A sealing member (not shown) may be coupled to lip 882 or doors 886.

As shown in FIGS. 67 and 68, upright portions 870 of rear roll cage portion 854 may support a hinge member 952. Referring to FIG. 89, hinge member 852 may be integrally coupled to a bracket 956, which is coupled to bracket 1152 with conventional fasteners 958. In particular, bracket 956 is coupled to top portion 1154 of bracket 1152. Hinge member 952 is configured to receive a hinge pin 954, which is coupled to doors 886. In particular, hinge pin 954 is coupled to a bracket 960, which may be supported on each door 886 with conventional fasteners 962. Hinge pin 954 may be received within hinge member 952 to rotate or pivot therein when doors 886 are opened.

When assembling doors 886 to rear roll cage portion 852, tools are not required because doors 886 are secured to rear roll cage portion 854 when hinge pin 954 is received within hinge member 952. As such, doors 886 may be easily removed from roll cage 850 by lifting up on doors 886 and moving hinge pins 854 away from hinge member 852. Furthermore, the vertical arrangement of hinge pin 954 and hinge member 952 may increase rigidity between doors 886 and roll cage 850.

Referring to FIG. 90, doors 886 are further secured to front roll cage portion 852 with a door latch assembly 964. Door latch assembly 964 includes latching arms 967 operably coupled to a door handle 969 and configured to receive a latching bar 966. In the illustrative embodiment, latching arms 967 and door handle 969 are supported on door 886 and latching bar 966 is supported on front roll cage portion 852, in particular on upright portions 856. Latching bar 966 may be coupled to upright portions 856 with a bracket 968. In operation, door 886 is closed when latching bar 966 is clamped between latching arms 967. When opening door 886, door handle 969 may be activated, which separates latching arms 967 and releases latching bar 966.

While door latch assembly 964 secures doors 886 to roll cage 850, the shape and structure of doors 886 may bias doors 886 toward the closed position. As best shown in FIG. 91, the top of doors 886 may be slanted or angled inwardly toward operator area 30 relative to the bottom of doors 886. More particularly, illustrative doors 886 include an approximately 2° vertical angle or taper at the top which gives doors 886 a tendency to close.

Doors 886 may be held in the open position with an auxiliary latching assembly 970. As shown in FIG. 92, auxiliary latching assembly 970 may be a buckle assembly coupled to rear roll cage portion 854 or rear windshield 890 and doors 886 (FIG. 68). Auxiliary latching assembly 970 includes a first latching portion 972 coupled to a first support member 974 and a second latching portion 976 coupled to a second support member 978. Referring now to FIG. 68, first support member 974 may be coupled to rear windshield 890 with at least one conventional fastener (not shown) and extend outwardly toward door 886. Second support member 978 may be coupled to door 886 with a conventional fastener (not shown). Second latching portion 976 and second support member 978 may extend rearwardly from door 886. Alternatively, first latching portion 972 may be coupled to door 886 and second latching portion 976 may be coupled to rear windshield 890. Auxiliary latching assembly 970 assists in limiting the angular travel of doors 886 in order to prevent doors 886 from over-rotating, which may damage to doors 886.

When door 886 is rotated to the open position, second latching member 976 moves toward first latching member 972 such that first and second latching members 972, 976 may be coupled together. In this way, first and second latching members 972, 976 hold door 886 in the open position (i.e., door 886 extends outwardly from vehicle 600 and is substantially perpendicular to longitudinal axis L).

Illustrative doors 886 include windows 980, as shown in FIGS. 67 and 68. Windows 980 may be configured to open to provide additional ventilation to operator area 30. For example, one end of windows 980 may be pivotally coupled to doors 886. The opposing end of windows 980 may include a closure member 982 that further secures window 980 to door 886. Closure member 982 may be coupled to door 886 and window 980 and may be movable to open and close window 980. Illustratively, window 980 is configured to open outwardly from door 886 rather than inwardly toward operator area 30, however, alternative embodiments of window 980 may be contemplated.

It may be appreciated that roof 884, doors 886, front windshield 888, and rear windshield 890 are removably coupled to roll cage 850. As such, roof 884, doors 886, and front and rear windshields 888, 890 may be easily assembled to roll cage 850. Likewise, roof 884, doors 886, and front and rear windshields 888, 890 may be easily removed from roll cage 850. For example, roof 884, doors 886, and front and rear windshields 888, 890 may be replaced, or interchanged with alternative embodiments thereof. Additionally, illustrative roof 884, doors 886, and windshields 888, 890 are modular and may be comprised of canvas, plastic, or such materials.

During assembly, cab 840 may be enclosed (i.e., isolated from the outside air) by coupling front windshield 888, rear windshield 890, roof 884, and doors 886 to roll cage 850 without conventional fasteners or couplers (e.g., bolts, welds). Cab 840 may be enclosed by assembling front windshield 888, rear windshield 890, roof 884, and doors 886 to roll cage 850 in any order. An exemplary assembly method may enclose cab 840 by initially coupling front windshield 888 to roll cage 850. In particular, front windshield 888 may be coupled to front roll cage portion 852 by resting front windshield 888 on the contoured portions of upright portions 856, overhead beam 858, and lower beam 862. Clips 910 or hinge assembly 916 may be coupled to front windshield 888 and front roll cage portion 852 in order to sealingly secure front windshield 888 to roll cage 850. In this way, front windshield 888 encloses the front of cab 840. Additionally, it may be appreciated that fasteners are not required to assemble front windshield 888 to roll cage 850.

Optionally, rear windshield 890 may be installed after front windshield 888. Rear windshield 890 may be coupled to roll cage 850 by resting against upright portions 870 and cross members 872 and 874. Clips 910 or clamps 946, 948 are used to sealingly secure rear windshield 890 to rear roll cage portion 854 and enclose the rear portion of cab 840. As such, rear windshield 890 is secured to roll cage 850 without conventional fasteners, which allows rear windshield 890 to be easily assembled to, or removed from, roll cage 850. Additionally, it may be appreciated that fasteners are not required to assemble rear windshield 890 to roll cage 850.

After front and rear windshields 888, 890 are coupled to roll cage 850, doors 886 may be assembled to further enclose cab 840 by positioning hinge pin 854 within hinge member 952. As such, doors 886 are hingedly coupled to roll cage 850 to enclose the sides of cab 840 and do not require conventional fasteners for assembly. Additionally, hinge pins 854 allow doors 886 to be easily removed from roll cage 850 by lifting doors 886 upwardly to disengage hinge pin 854 from hinge member 952. It may be appreciate that tools and fasteners are not required to assemble doors 886 to roll cage 850 or to remove doors 886 from roll cage 850.

Lastly, roof 884 may be coupled to roll cage 850 to fully enclose cab 840. In particular, front locating members 898 may be positioned through apertures 861 of beam 858 by tilting the rear of roof 884 upwardly to angle front locating members 898 relative to apertures 861. When front locating members 898 are positioned through apertures 861, the rear of roof 884 may be pressed downwardly such that rear locating members 898 engage with apertures 873 of cross member 870. More particularly, rear locating members 898 may be snapped or latched into apertures 873 to sealingly retain roof 884 on cab 850. In this way, it is not necessary to secure roof 884 with conventional fasteners (e.g., bolts, welds). By eliminating the need for conventional fasteners, roof 884 may be easily assembled to, or removed from, roll cage 850.
